L&#39;aumento preoccupazioni per quanto riguarda l&#39;afflusso di specie invasive agricole hanno portato ad un aumento della domanda di nuove metodologie per la difesa contro i parassiti e patogeni emergenti. Un focus di prevenzione e gestione della malattia comporta la gestione di vettori patogeni ed era l&#39;obiettivo primario di questo studio. Economia svolgono un ruolo fondamentale nella decisione di produrre questo tipo di biopesticida per gestire vettori di patogeni in agricoltura perché l&#39;applicazione prat...

Il cecchino vitreo-alato (Homalodisca vitripennis Germar 1821) è stata identificata come il vettore predominante di Xylella fastidiosa (X. fastidiosa), l&#39;agente causale della malattia di Pierce della vite (PD) in Nord America 1. Insetto gestione della popolazione è rapidamente diventato il centro della ricerca per combattere questo problema devastante per il settore della viticoltura in California e in tutto il sud degli Stati Uniti. Un positivo-senso, virus a RNA a singolo filamento appartenente alla famiglia Dicistroviridae, Homalodisca virus-01 coagulata (HoCV-01) è stata identificata in H. selvatici popolazioni vitripennis e dimostrato di aumentare la mortalità in quelle popolazioni 2-4, riducendo al contempo la resistenza degli insetti agli insetticidi. Sviluppo di metodi per efficacemente posteriore infetto H. vitripennis all&#39;età adulta in un ambiente di laboratorio sono stati difficili perché <em&gt; H. vitripennis hanno diverse esigenze nutrizionali specifiche fasi che richiedono una grande varietà di piante ospiti 5-8. Strutture specifiche sono richieste per posteriore H. vivo vitripennis negli Stati Uniti; Pertanto, coltura cellulare è più economico e una possibile alternativa, così come sempre più vitale per HoCV-01 rilevazione e replicazione 2,9. Mentre i metodi di base per stabilire colture cellulari di H. vitripennis sono descritti, questi metodi non sono ancora stati utilizzati per la produzione commerciale di agenti di controllo biologico, come ad esempio i virus 2. L&#39;obiettivo generale delle seguenti procedure è quello di produrre una elevata concentrazione di HoCV-01 adatto per l&#39;utilizzo come agente di controllo biologico. Replicazione virale richiede una cellula vivente, che è il motivo per cui coltiva con successo e l&#39;ottimizzazione H. vitripennis culture è fondamentale per il progresso di produrre livelli redditizi di virus.

propagation of homalodisca coagulata virus-01 via homalodisca vitripennis cell culture

Il cecchino vitreo-alato (Homalodisca vitripennis) è un insetto estremamente polifago vagili e presente in tutto il sud-ovest degli Stati Uniti. Questi insetti sono i vettori predominanti di Xylella fastidiosa (X. fastidiosa), un batterio xilema limitata che è l&#39;agente causale della malattia di Pierce (PD) della vite. Malattia di Pierce è economicamente dannoso; così, H. vitripennis sono diventati un bersaglio per le strategie di gestione del patogeno. Un dicistrovirus identificato come virus-01 Homalodisca coagulata (HoCV-01) è stata associata a un aumento della mortalità in H. popolazioni vitripennis. Perché una cellula ospite è necessaria per la replica HoCV-01, coltura cellulare fornisce un ambiente uniforme per la replica mirato che è logisticamente ed economicamente importante per la produzione di bio-pesticida. In questo studio, un sistema per la propagazione su larga scala da H. vitripennis cellule tramite coltura tissutale è stato sviluppato, providing un meccanismo di replicazione virale. HoCV-01 è stato estratto da insetti di tutto il corpo e utilizzato per inoculare H. colta vitripennis cellule a diversi livelli. Il terreno di coltura è stato rimosso ogni 24 ore per 168 ore, RNA estratto e analizzato con qRT-PCR. Le cellule sono state colorate con blu trypan e contati per quantificare la capacità di sopravvivenza delle cellule mediante microscopia ottica. Particelle virali intere sono stati estratti fino a 96 ore dopo l&#39;infezione, che è stato il punto di tempo determinato per essere prima totale coltura cellulare crollo si è verificato. Le cellule sono state inoltre sottoposte a colorazione fluorescente e visualizzati mediante microscopia confocale per indagare l&#39;attività virale su attaccamento e nuclei integrità F-actina. La conclusione di questo studio è che H. vitripennis cellule sono in grado di essere colta e utilizzata per la produzione di massa di HoCV-01 a un livello adeguato a consentire la produzione di un biopesticida.

Attaccamento delle cellule e la crescita è stato visto in 48 ore di passaggio in piccole e grandi fiasche di coltura, da colture primarie e continui passaggi. Crescita dei fibroblasti e sviluppo è stata osservata anche in questo lasso di tempo. Quando fiaschi appena seminati sono stati disturbati prima di 48 ore, c&#39;è stato un calo visibile in adesione cellulare, portando a culture crescita più lenti ea volte senza attaccamento o di crescita a tutti. Le cellule sono state circa il 80% confluenti entro una settima...

Propagazione di<em&gt; Virus-01 Homalodisca coagulata</em&gt; Via<em&gt; Homalodisca vitripennis</em&gt; Cell Culture

Qui vi presentiamo un protocollo per propagare le cellule Homalodisca vitripennis e HoCV-1 in vitro. Media è stato rimosso dalla HoCV-1 colture positive e RNA estratto ogni 24 ore per 168 ore. Sopravvivenza cellulare è stata quantificata trypan colorazione blu. Particelle virali intere sono stati estratti dopo l&#39;infezione. RNA estratto è stato quantificato da qRT-PCR.

The glassy-winged sharpshooter (Homalodisca vitripennis) is a highly vagile and polyphagous insect found throughout the southwestern United States. These ...
